That's actually objectively pretty high if we're talking prospects - it's more than just skill, buzz counts as well. Of course you have to win, but the path goes through opponents that offer a higher reward
Both guys have clearly caught the eye of WME and the winner will be in title contention in a year or two if they can manage to win fights, that much is clear

The winner of that fight will be pushed pretty hard
He's more skilled than both, I think by a good margin, and more experienced (despite being around the same age as Gall)
